Tempest (video game)

Tempest is a 1981 tube shooter video game developed and published by Atari, Inc. for arcades. It was designed and programmed by Dave Theurer. It takes place on a three-dimensional surface divided into lanes, sometimes as a closed tube, and viewed from one end. The player controls a claw-shaped "blaster" that sits on the edge of the surface, snapping from segment to segment as a rotary knob is turned, and can fire blaster shots to destroy enemies and obstacles by pressing a button. Tempest was one of the first games to use Atari's Color-QuadraScan vector display technology. It was also the first to let players choose their starting level (a system Atari called "SkillStep"). This feature increases the preferred starting level, which could also be used to let the player continue the previous game if they wished. Tempest was one of the first video games that had a progressive level design where the levels themselves varied rather than giving the player the same layout with increasing difficulty.
